A further object aims at providing stationary bearingsmembers constituting pivots for the win- ;dow sashes so that the latter-may be swung in- ;wardly-at predetermined portions.

which'the invention .is predicated. I

The lowerwindowsashi 2 is provided near the bottom and at eitherpend with a bracket M (Fig. 5) which has 'a, projection I5 riding in a vertical f Secured to the window framelll and alignof the com the upper edge of the I Chicago. Applicatio'n May 2, 1935, Scrial No. '1 9,436.. QT Claims. (01. -43) ment" with the slot I6 is a bearing member of angular form (Fig. 7) comprising a face plate l8 having a plurality of holes l9 to receive screws permitting the bearing member IT to be secured in a rabbet of the window frame Ill. The face l8 extends into a flange 20 at right angles thereto and provided with a horizontal lug 2| formed with an-ape'rture'22. The face plate has a large opening 23 leading'to a vertical slot 24 terminating at the upper end of the plate.

A vertical rod 25 extends through'the aperture 2| and is held at the upper end by a clip 26 (Fig. 2)- The rod is encircled at theupper end by a coiled spring 2! bearing at one end against said clip and with the other end against a blade 28.

- at either side thereof which selectively enter apertures 3| in a guide member 32. If it is de- I sired to rotate the window, the bolts 30 are drawn inwardly and thereupon the sash is swung about its pivots l5 which in the lower position extend into the openings 23.

The upper window sash II is also provided with brackets 33 having projections 34 which are uided in slots 35 in the window frame l0. As shown in Fig. 4 chains or cords 36 and 3'! respectively'are secured to the projections 34 and I5 and are trained around pulleys or sheaves 38 and 39, respectively, to be secured to the usual sash weights 40.

The upper sash II is guided and held in alignment by a flange 4| of a vertical member 42 and an additional guide member 43 mounted intermediate the sashes H and I2. The member 43 terminates asat. 44 anda similar member 45 is secured to either side of thesash.

Mounted on the frame I0 is a bearing member I 46 (Figs. 2, 6) provided with an opening 47 extending into a slot 48. through which enters the projection 34' of the-sash bracket. If it is desired to rotate the upper sash lug 34 is within theopening 41. In this position sash II has cleared the member 43: and the sash may now be swung inwardly until it assumes a horizontal position; As will be seen from Fig. '4, the members 42 and 43 serve as weather strips for the upper sash.

The lower sash l2 abuts against weather strips 49 (Fig. 5) which are provided with a channel 50 to receive a wiping member 5| secured to the sash I2.

Attention is called to the fact thatblades 28 are spring ,thrust into closed position by asp ring 21 shown in Fig. 2, so that upon swinging'the lower sash inwardly and upon return of tion the blades automatically thesash into vertical posi or full line position shown in Fig. 4.. I

While the drawings show a preferred. embod changes and alterations may be made without departingfro-m iment ofthe invention, numerous the spirit of the invention.

I, therefore, do not limit myself to the details of construction and arrangement as shown, but claim my invention as broadly as the state of the art permits.
